之前Run的時候還ok 突然就出現這個問題
換了別台電腦試也是一樣會發生問題 請各位幫我看看哪裡寫的不好
需要改進的~
或是該怎嘛Debug 小弟是初學者 不太會使用:D
執行失敗時 指標有停在 usersession.UserAimage:=sum[0].path;
這一行

引言: inglong 沒看到usersession的Type及宣告? Sum[]在出問題點的前面就已經執行過,而且有配置空間及執行過 或許您可以用逐行執行程式的方式，看這兩個變數在記憶體中是否有配置， 或看看真正停在那一行出現錯誤 ................... .楛耕傷稼,楛耘失歲. ...................usersession的宣告我寫在這裡 interface uses SysUtils, Classes, IWServerControllerBase, // For OnNewSession Event IWApplication, IWAppForm; type TIWServerController = class(TIWServerControllerBase) procedure IWServerControllerBaseNewSession(ASession: TIWApplication; var VMainForm: TIWAppForm); private public end; // This is a class which you can add variables to that are specific to the user. Add variables // to this class instead of creating global variables. This object can references by using: // UserSession // So if a variable named UserName of type string is added, it can be referenced by using: // UserSession.UserName // Such variables are similar to globals in a normal application, however these variables are // specific to each user. // // See the IntraWeb Manual for more details.
